4WE6E6X/EG24N9DK35LSO43A-1807 CSA

The 4WE6E6X/EG24N9DK35LSO43A-1807 CSA valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and is built to shift hydraulic flow paths in automated machinery. Its solenoid is designed for a nominal voltage of 24 V DC, so standard control cabinets can energize the spool without a separate converter. At 30 W of nominal power and a rated current of 1.25 A, the coil provides reliable force while keeping heat generation moderate. An M12×1 four-pin connector streamlines hookup to field wiring and maintains tight sealing around contacts. Continuous operation is possible because the duty cycle is 100 % S1, eliminating timing constraints during long hold periods. The actuator can change state up to once per second, the specified maximum switching frequency, which matches typical cycle rates in servo-hydraulic loops. A concealed N9 manual override lets maintenance staff shift the spool during commissioning without exposing moving parts. Mounting follows the ISO 4401-03-02-0-05 porting pattern, and a mass of 1.95 kg simplifies manual installation.

For circuit performance, the directional valve withstands 350 bar on ports P, A, and B, permitting use in high-pressure supply manifolds. The direct-current solenoid can pass up to 80 L/min, so medium-flow actuators reach full speed without additional throttles. Return flow sees 210 bar permitted on port T, allowing back-pressure applications such as counterbalance circuits. Protective design is verified by an IP65 rating, meaning sprayed water and dust do not impair the enclosure in typical plant environments. Hydraulic cleanliness should not exceed ISO 4406 class 20/18/15, a level that prevents spool scoring and leakage paths. The body interfaces with NFPA D03 subplates, ensuring interchangeability with common North American stack patterns. Overall ingress resistance and standardized mounting make the valve suitable for decentralized servo blocks where environmental exposure is expected.
